Will Natural Herd Immunity End the Pandemic?
Is natural herd immunity a viable path to controlling the pandemic? Here is why that is a terrible idea.
Herd Immunity
Some infections can be eradicated from the face of the planet. Smallpox is the one example of disease eradication to date. Smallpox still exists in US and Russian labs, but there has been no wild cases since 1977. It is, like the Dorothy, history. Why were we able to eradicate smallpox? Three reasons: 1) There is only one form of smallpox. Unlike...
The horrible consequences of seeking “natural” immunity: Naturopathy and Whooping Cough
If there’s one area of “alternative” medicine that saddens (and angers) me, it’s the antivaccine movement. Most alternative medicine only risks harm to the user. But antivaccinationists threaten public health. Their actions can harm the most vulnerable in our society – often children, and others who depend on the herd immunity that vaccination provides. After my last few naturopathy vs. science posts...
Immunity: More Than Just Antibodies and Vaccines
Since I graduated from medical school, new scientific developments in immunology have been occurring at a prodigious rate. I knew I could use a refresher course, and serendipity dropped one in my mailbox in the form of a review copy of the new book Immunity, by William E. Paul, MD, chief of the Laboratory of Immunology at the National Institute of Allergy...
The problem of waning pertussis immunity
There’s been a lot of discussion, both in the scientific literature and online, about recent pertussis outbreaks, which are the worst outbreaks in the US in the last 50 years. How could this possibly be, it is asked, when vaccine uptake for the pertussis vaccine remains high? True, there are pockets of vaccine resistance, where uptake of the vaccine is low, but...
You can’t hide in the herd
Can you hide in the herd? Well, I suppose the title has given away the punch line. Herd immunity is a fascinating effect, and one of the mainstays of a public vaccination effort. The idea is that if enough people in the community are immune to a particular disease, then those who are susceptible will rarely come into contact with a person...
COVID-19 and balancing the risks: The vaccine or the virus
Given recent reports of myocarditis after vaccination with mRNA-based COVID-19 vaccines in young people, we think it's a good time to reexamine the risk/benefit ratio of these vaccines in this population.
The Delta Variant
The emergence of the delta variant of SARS-CoV-2, leading to more cases of COVID-19, is a reminder that we have not won this race against the pandemic yet.
The Causes of Vaccine Hesitancy
The vaccine hesitant are now the front lines of the battle to contain COVID.
How antimaskers weaponize techniques of scientific analysis to attack mask mandates
There's a new paper out analyzing how antimask activists weaponize the tools of data visualization and scientific argumentation to produce convincing antimask propaganda. Antimaskers are claiming that it shows that they are more "scientific" than those supporting the consensus viewpoint with respect to COVID-19 and masks. What it really shows is that they are good at weaponizing the tools of data visualization...
